The average that one person spends on a cup of coffee at Starbuck's or an equivalent coffee shop is $5.00. This does not include any tip. $5.00 multiplied by 30 days is $150.00 a month! If you are getting 2 coffees (as my case with my girlfriend) that can add up to $300.00 a month!
The mark-up on coffee is insane! In many cases it is up to 500 percent or more!
Coffee at home averages about .10 to .50 cents a cup. Big savings!
P.S. If you do find yourself getting coffee at a shop... Try to stay away from the big corporate places. Support someone who is working hard for the money instead. :) Plus... They are usually cheaper and better.
